To all 'wwmz't may concern.'

sliding connection n lhousing and part of the Be it known that I, HENRY RUPPEL, a\Qil-feed pipe shown in vertical section.

citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Blue-Flame Oil-Burners, of which the following is a specification, reference being had therein to `the accompanying drawing.

This inventlon relates to improvements in blue flame oil burners, and is of that type which has been known in the art for a great call many years as the wickless blue flame. oil burner, in which there is a trough in which the oil is fed, the trough containing an initial lightingfmember.

The inventionlso pertains to that type of wickless blue flame o1l burner in which the trough is vertically adjustable for controlling the level of the oil in the trough. This has also been known to the art for a great many years.

One object of my invention is to provide an improved sliding connection through the medium of which the trough is raised and lowered, whereby a free movement is th provided while at the same time a practioil-tight sliding connection is accomplis ed.

Another object of m invention is the provision of a housing or the sliding connection which is provided with a closed bottom to receive any slight leakage that may possibly occur from wear of the parts, and in which housin the leakage is vaporized by the heat con ucted. from the burner to the housing, the vapor passing up through the housing into the combustion chamber.

A further object of my invention is to utilize the connection housing and a yoke' loosel engaging the connection for raising and owering the sliding connection and thereby the trough.

Further ob'ects of my invention will appear from t e following description and disclosure.

In the accompanying drawings:

Figure 1 is a side elevation of my burner shown in connection with'a part of a frame and a maintained level oil feed, the latter shown in vertical section.

Fig. 2 is an enlar ed central sectional view of my improvediurner.

Fig. 3 is a side elevation of my burner, the

n carrying out my invention, I utilize any, deslred form of burner supporting frame .1, at the bottom of which is a suitable o1lfeedin pipe 2. This oil feeding p1pe 2 communicates with a pi e 3, which in turn communicates with a wel -known form of maintained oil level feeding device A. Since the construction and principle of operation of this oil-level feeding device A, has been well-known in the art for many years, 1t 1s unnecessary to give any detail construcltion thereof. y

y improvement utilizes the well-known annular trough B, which contains also the well-known initial lighting or starting member C. Detachably seated on the upper end of the trough B, is the Well-known perforated combustlon section D, which is surrounded by the well-known hood E, for protecting the combustion section from air drafts. As the foregoing elements of a blue-flame oil burner are Well-known inthe art, it is unnecessary to give any detail construction' of In vcarryin out my im rovement I rovide a membr F which epxtends transvlrse the trough B and is located below the trough. The ends 4 of this member F are suitably shaped to receive the bottom of the trou h, and the ends 4 and the trough arel suitaly connected, preferably by brazing or soldering. This member F, at one side of its center is solid, as at 5, and the other side is tubular, as at 6. This tubular portion 6 communicates at its outer end with the bottom of the trough B, through an opening 7 An elongated sleeve 8, which ,is preferably integral with the member F, projects downward therefrom and is in communication with the inner end of the tubular portion 6. A tube 9 projects upward from the member F, and has its upper open end l0 substantially in the horizontal plane of the u per end of the trough. An elongated tuge 11 has its lower end 12 connected in any suitable manner with the oil feeding pipe 2, and extends upward into the elongated depending sleeve 8. The vertical passa e 12 into which this elongated tube 11 sli es, has its u per end 13 contracted and the upper end o the assage l2 is tapered as at 14, to receive the corresponding tapered end 15 of the elongated tube 11. The exterior surface of the tube l11 and the passage 12 have a machined fit so that practically an oil fit is made between them while at the same time ,the sleeve 8 can freely move vertically von the tube 11. The /tapered'portions 14 and 15 of the passage 12 and the upper end of the tube 11 form a valve seat for a purpose v tical lslots 20, and the ends of the member F have laterally projecting lugs which extend intoA these slots and move therein as the trough is raised and lowered. rBins construction prevents any turning movement of the trough.

A collar 22 surrounds and loosely fits into an annular groove 23 formed in a sleeve 8. The lower wall of the groove 23 is formed bv an internally screw-threaded collar a,

` fitting a screw-thread 16 of the sleeve 8.

This collar a is therefore adjustable in reliation to the loose collar 22, and is held in 1ts adjustment by a suitable screw b passing therethrough to engage the screw-threads 16. This collar 22 carries two laterally proj eating rods 24 and 25 which project through oppositely disposed inclined slots 26 and 27, formed in the housing G. These rods 24 and 25 are smaller in diameter than the width of the slots 26 and 27, so that rollers 28 may be placed on the rods for engaging the upper and lower walls 26' and 27 of the slots 26 and 27. The rod 24 projects beyond the housing G, as shown and receives a suitable handle 29. ,j

By pushing the handle laterally the rods and their rollers will travel in the inclined slots 26 and 27 and through the medium of the collar 22 and sleeve 8, cause the trough to be raised or lowered according to the direction in which the handle 29 is moved.

A slot 30 is formed in the housing Gr above its lower end through which a suitable wrench may be passed for adjusting the stuiling box 17, and the wall of the housing G, is also provided with a plurality of open ings 31 above its bottom.

In operation when the trough B is in its lowered position, the oil in the trough will be of a height corresponding to the oil level of theoil-level feeding device A, as will be readily understood, and at its greatest depth in the trough. With the trough in this pober havingi sition, the burner is burning full flame and the tapered portions 14 and 15 form, in effeet, a valve seat, thus relieving the passage 12 and the stufiing box 17 of any o1l pressure. Owing to the elongated' machined bearing surfaces ofthe sleeve 8 and the tube 11, a practical oil sliding connection is formed, but should there be any seeping of oil from this sliding connection when the burner is standing unlighted or otherwise, it will be collected in the bottom of the houslng G, and when the burner is lighted and becomes heated, heat is conducted from the burner trough to the housing G, and the oil seepage w1ll be vaporized in the housing and the air drawn through the openings 31, slots 30, 26, 27 and 20 causes an upward draft carrying the vapor intoVV the combustion chamber above where it is consumed. A1r reaches the interior of the combustion` section through the above-mentioned openings and slots and the housing in` addition to serving the functions already described, and it further serves to cause a feed of air which is distributed and protected from external air drafts.

Owing to the open end 10 of the upwardly extending tube 9 and the large passages 6 and 7 the oil quickly flows from the trough when 1t 1s elevated and quickly iows into the trough, when it is lowered. Attention is directed to the fact that the tube 9 is in a line with the tube 11, so that a wire can be readily passed through the tubes 9 and 11 to the large oil feeding pipe 2, for the purpose of dislodging any collected sediment or other foreign matter which might interfere with a free flow of the oil to and from the burner trough B.

By providing the troughwith a depending tubular sleeve 8 and extending a tube 11 from the oil-feeding pipe 2, I provide an elongated bearing for the sliding connection whereby practically an oil-tight joint is formed with but little friction. v The stuiiing box 17 is not essential in this construction, but 1s used primarily as a safety device should the sliding connection be subjected to some unnatural condition or use.
